About

A team building the audit infrastructure for biochar.

We started Biochar Systems UK because the spreadsheets had to go. Producers were doing serious work; the tooling around them looked like 2008. We're closing that gap, one batch at a time.

Our mission

Make every UK biochar credit defensible — by default.

The carbon market is moving from claim-based to evidence-based. We want the UK biochar industry to be ready for that shift with the infrastructure already in place — not bolted on after the first hard audit.

  • Evidence over rhetoric

    If we can't show the workings, we don't ship the number.

  • Small surface, deep utility

    Fewer features, used by every producer every day.

  • Producer-first

    The platform earns its keep on the producer's side. Buyers benefit second.

  • UK-grounded

    Hosted, supported, and accountable in the UK.

Where we operate

UK-first. Built to scale to the rest of Europe next.

We work with UK biochar producers, agricultural co-ops, and forestry operators today. The platform is methodology-agnostic and ready to follow producers into adjacent EU markets.

Producers

From farm-scale to industrial pyrolysis sites.

Co-operatives

Aggregating biochar from a network of smallholders.

Buyers

Corporate offtakers who need provable, retire-able credits.

Auditors

External verifiers who need scoped, read-only evidence.
